We all know that natural gas is a flammable and explosive gas. As an important clean energy, it has been widely used in many industries. Due to the flammability and explosiveness of natural gas, we must pay attention to the concentration of natural gas leakage when using natural gas to prevent the occurrence of natural gas explosion accidents. To prevent natural gas leakage and explosion accidents, we need to install and use natural gas alarms to detect the concentration of natural gas. The main function of natural gas alarms is to detect the concentration of natural gas leakage. Once the natural gas leakage reaches a certain concentration, the natural gas alarm will automatically sound. The light alarm reminds the staff to take corresponding measures in time to avoid major accidents. Natural gas alarm is an important security facility. The alarm value of natural gas alarm is generally divided into one level and two levels. Today we are mainly here to explain why this natural gas alarm needs to be equipped with two levels of alarm? What are the benefits?
The first-level alarm device can realize the activation of the solenoid valve or the exhaust fan when the equipment alarms. The second-level alarm device can realize dual-pipe supervision, that is, when the natural gas alarm detects that the concentration of natural gas exceeds the first-level alarm value, it indicates that there is a natural gas leakage, but the natural gas leakage is not much, so when the first-level alarm is selected, start the exhaust fan. It can reduce the concentration of natural gas and ensure environmental safety. When the measured natural gas concentration reaches the second-level alarm value, it indicates that a large amount of natural gas leakage occurs. At this time, using the exhaust fan to disperse the problem can not solve the problem, so choose to activate the solenoid valve when the second-level alarm is activated, and directly cut off the gas pipeline. Afterwards, apply soapy water to the natural gas pipeline, and the place where bubbles are formed is the natural gas leakage point. Take remedial measures after leaks are detected.
